@Sarah-Ginga O.o...I am honored that your mom knows about me. Haha, wow. I can't believe your comment. It's just so...wow. Your totally right, your comments make my day and make me smile. Don't say you're a terrible writer. Ever. Anyone can be a great writer as long as they keep practicing.
If you think you're bad, you should see some of the things I've written before I started to get serious about it. (I wrote a story about a magical forest that transported people to a place with talking birds...O.o..) Just pay attention in classes like English and stuff. Even though they are incredibly boring (I know, I know) they can help you with your grammar and style.
Thank you so much for being an amazing reader and just keep working at your writing! :D
